HTS Chapter 3 — Fish, Crustaceans, Mollusks Tariff Rates (2026)

Chapter 3 of the HTS — Fish, Crustaceans, Mollusks — is among the most tariff-impacted categories in US trade. Covers fish (live, fresh, chilled, frozen), crustaceans such as shrimp and lobster, and mollusks such as oysters, clams, and squid. The average MFN (Most Favored Nation) duty rate for products in this chapter is 1.2%. Individual rates vary significantly within the chapter, ranging from duty-free to well above the average. In addition to MFN rates, most non-EU imports face the 10% Section 122 tariff (effective February 24, 2026; scheduled to sunset approximately July 24, 2026). EU-origin goods instead fall under the EU-US trade deal's 15% all-inclusive ceiling (effective July 1, 2026) — MFN does not stack on top, and goods with MFN rates of 15% or higher pay MFN only. Chinese imports in this chapter face additional Section 301 tariffs ranging from 7.5% to 100%, depending on the specific product classification. Common products in this chapter include Fresh salmon, Frozen shrimp, Lobster, Tuna, Crab meat, Oysters, Squid and octopus, Tilapia fillets, Cod. Related HTS chapters include Chapter 1, Chapter 5, Chapter 16, which cover similar or complementary product categories.
